I have lived here for over 40 years in an old suburb.There have always been fox squirrels around. They even nested in the two Siberian elm trees in my yard until the trees were removed.I NEVER say a gray squirrel in all those years until last year. Now there are more of them.The neighbor across the street sets out corn for them and during feeding time there will be up to 18 squirrels (the most I have been able to count) running around, climbing trees and chasing each other. About 1/5 of them are grays now.Anyone else ever seen another type of squirrel move into a neighborhood?Are the grays likely to take over?I would have thought the bigger fox squirrels would be able to hold their own.Gary
